Tetrabutylammonium difluorotriphenylsilicate

Tetrabutylammonium difluorotriphenylsilicate is a model system for studying the mechanism of nucleophilic substitution at an unsymmetrical carbon center. It is used in analytical chemistry to prepare samples for analysis. Tetrabutylammonium difluorotriphenylsilicate has been shown to be an effective and selective reagent for the synthesis of picolinic acid, which can be used as a precursor for the synthesis of nicotinamide riboside, a vitamin B3 derivative. The reaction proceeds via an SN2 mechanism, where hydrogen fluoride (HF) acts as a nucleophile that attacks the electrophilic carbon center of allyl chloride (CH2=CH-CH2Cl) to form an intermediate with two alkyl groups on opposite sides. The reaction product is then hydrolyzed to release tetrabutylammonium chloride (tBuNH4Cl).
